I've been doing more work on better blobs, here's the results. These 
blobs are as easy to control, since they use a bounded function, unlike 
the exponential blobs where adding one blob affects the whole object.

They are quite a bit slower as an isosurface with user-defined 
functions, I plan to make a pattern patch though. Being compiled alone 
will make it much faster, and it will make some optimizations possible. 
I have no idea how to add it to the blob object, or even if it is 
practical, but an object with the isosurface solving method could still 
make more optimizations than a simple pattern.

The smooth ones are the isosurface versions. I tried to duplicate the 
"open" one with blobs, but it would require a fifth blob component at 
the center, so I went back and tried to duplicate the real blob with the 
new blob function instead. As you can see, there are definite 
differences, you can't just throw it in as a replacement, but it is 
close.
